Total integrated simulation technology for fuel pump with system-fluid-magnetic co-simulation

Automotive fuel can be efficiently combusted by injecting it into the cylinders at high pressure to atomize it to pass gas and fuel economy regulations for exhaust. Automotive companies have developed direct injection engines, which inject gasoline directly into the cylinders. Demand for quieter hig...
